2 (@310 lotilli) invention reletee to improvements in burners of the convention type in which a; burner may he placed into e furnace or Iceoiwr designed initially for the burning of solid tool. 5 in gas burners oi the conversion type till here toiore mode, it has been common practice to provide heiflee extending e. on inclination across the flame and supported at their lower edges on or near the burner and resting at their upper to edges against the luroece well. Such homes have the dissdveotoge that the inclination of the lociflee and the clistooce from the gas discharge ori flees to the loefie ie dlfiererot in clifierent instellw tioos, depending upon the distence or the furnace to wallfromtloe tumor. The emciericy oi such bum ere, therefore, verieo in different iootelletiozoe. Flame-deflecting devices mounted on oz moor the burner and extending toworcl tire iiuiiece well, i but not contacting therewith, hove moo hereto 94o tore oeeo mode, hut such devices were not of constructione which permit the use of euhstericee which become luminous when highly lieeteol, end which, therefore, have it high emcieocv in the recitation of heat,

The objects of this invention ore toproviole e burner of this kind having at flame deflecting de vice arranged to deflect the flame outwardly toward the well of the furnace in which the isomer is installed, in which this get deflecting tie- I m vice is to sections adapted to be supported olde by side end held in upright operative position by means engaging the'lower ends of the sections; ole-o to provide e flame deflecting device of this kind in which the individual sec $5 tioris or bellies are teamed with looses oi to m proved construction :lor coogleretinzz with grip plug meant to hold the bellies in correct positions; also to provide as comer which provide-cl with gripping moons of im ii'oved construction for co 4o operating with the base oil the homes; also topicvide bofiee oil-this kind heaving upper tioos curved or fiored outwerdly ea c increasing angle to the vertical to deflect the time and hot eeseo towerd the turns-ice well it with e etreom lirie sweep, to produce more'eiiil cieut treosler oi loeot to the iurooce well; clue to improve the construction of ,g liumero of this kind in other respects hereioeiter ooeciileol.

Jln the accompanying drawing, A represents 8 burner oi any suitable or usual construction and which may he mode in two halves, es indicated v in Figs. 1 and 2. Each half of the burner in the 65 construction shown is provided with gas from an inlet pipe 10 communicating with a gas passage 11 formed ill. the burner and the ages passage supplies easto e. series oi upright discharge nozzles or tubes 12 terminoting short of. the upper wall 70 it of the burner, end each projecting it current of upwardly through on orifice or opening 14 in the upper well 13 of the burner Air is free to enter into the space or passage 15 of the burner and surrounds the gas discharge nozzles 12, and 75 thus is elected with the ges jets through the orifices and thoroughly mixes with the gas. Any other moons for supplying a combustible mixture may locprovided.

When the combustible mixture is ignited, a so flame will be formed alcove the orifices 14 end preiereblythie iieme impinges upon at flame defleeting device B, which is preferably made of suitable material having high efllclency in ra dioting heat. A suitable. refractory material or so clay commonly used in the manuiacture of radi-' out elements or bellies is preicrably employed. The flame deflecting device B is formed in a series of individual ioeifleo or units 18 which may be err-caged edge to edge to abutting relation co 'eo co to term o substantially continuous annular flame deflecting device, the individual bellies belug smell enough to pass through the feed doors of furnaces in which the burner is to he installed. The flame deflecting device may also be provided as on the portion thereof aeciost which the flames impinge with oroiections of may suitable kind, cucli o series oi beads or ribs 19 shown on the oeiiiee it, for the usual purpose of having these projections become heoted to high temperatures. loo

tlce-l. Title; time the limo "end hot was to no he gruduslly deflected outwardly so as to hnpinge against the furnace well, end thus flow upwardly along the furnace well to heat the same. In this manner, the gases are deflected by the bellies without producing eddy currents or otherwise interfering with the correct deflection oi the hot gases outwardly so thst they impinge at the desired angle ogeinst the furnace wall, Fig. 1, and flow upwardly slung the well to import heat to the well,

The lower ends oi the homes are suitably or runged to he gripped for holg the some in their upright or operative positions. In the per ticuler construction shown in Figs. 1 to d, the gripping devices for the lower ends of the rsdient bodies are formed inthe top well 13 of the burner and include upwsr end outwardly extending hooked lugs or projections 20 adapted to engage with sun inwerdly extending flenge or toe por tion 21 formed at the lower end of each of the bitfies is. The top wall'l3 of the burner is prelershlyelso provided with an annular wall or head 22 which extends only slightly shove the top well of the her.- in the use of this construction, the bullies ere pieced into operative relation to the burner hy first inclining the upper portions'thereoi towsrd the central unis of the burner so as to hook the toe portion 21 of the heffie under the lug 20) of the burner and the befiies are then s into the position shown in Fig. 3. When in this position, the ring or flange 22 will prevent the movement of the hose oi the hsifie away from the hooked portion 20, so

. that the homes will remain in their operstive positions unless removed by first swinging the upper portion of eech heme inwardly toward the central vertical sxis of the humor. By me of this construction, the parts of the heme ere securely held in their operative positions by the gripping flange or hook member 2h which pre vents the homes from tipping outwardly because of the overhanging or outwerdly curved part thereof. The lower ends of the hsihes, and e top of the burner are comparatively cool so thet there is no tendency of these ports to become deteriorated by host end the lower ports oi the bodies also are not weehened when the upper portions thereol hecome highly hoot/ed. In the construction shown in Figs. d end 6,

another form of grippm device forthe hottoin portions oi the hniiies is illustreted. In case, the lower ends of the bullies extend suhstentislly straight do end s portion of the or face of each hsffle mey he provided with en inwardly extending lug or rih 25, oi ineterielly less width then the lower port of the holds. The lower ends oi the hsiiies in case ere set vertically downwsrdly between two upwerdly extending flanges 26 end 27. These ges moy be cost integrally with the upper well it of the burner, and in order to nvoid the necessity of machining these ges to provide at tight ht with the lower ends of the hefies, the nesrwer extending lug or projection 25 is provided, the

or face oi which mey he scraped or cut down fin suitehle manner, so that the lower end oithe iodide will fit snugly between the flenges 2d and 27. Consequently, the homes will he held in their operative positions and prevented from tipping hecuuse oi the outwardly during parts oi the iodides. The dripping devices for the lower ends of the heiiies in the two constructions illustreted are shown. us formed on the top well or the burner, but it he understood thnt s sepe menses rote support for the hufiies with gripping devices for the lower ends thereof may be employed.

By me of the construction described, the baffies can be made of relatively thin material and can be given the required amount of out= word here to deflect the gases as may be nee esssry, and own he held in their operative positions by means engaging portions of the bullies not subjected to heme or to high temperatures. Any metsl retsining means engaging the upper hosted portions of the homes becomes rspidly corroded by the notion of the flame sndhest and con, therefore, not be relied upon to hold the homes. Bellies hsve also heretofore been made oi fire clay or inexpensive msteriels with bases sciently heavy to enshle the bodies to stand in their upright positions, but the cost of such construction is prohibitive in connection with bellies mode of c clay or similar msterisls used for producing homes of high hest radiating properties.
